Azure has release a new service called Azure Container Instances (ACI) that makes containers a first-class object of the Azure platform. It allows deploying container instance without having to provision, configure, or maintain underlying servers or hosts for those containers. and the great thing about this is you get billed the second for containers, not servers.

Containers have fundamentally changed the way applications are developed, built, and deployed. And the way system administrators manage their environments.

The benefits of using azure container instances are

Fast startup times. Containers can start in Azure in seconds compared to VMs that takes a long time.

Hypervisor-level security. Application are isolated in a container as it would be in a VM.
